CHURN.

SPECIFICATION forming part of Letters Patent No. 433,059, dated July 29, 1890.

Application filed March 22, 1890.

To all whom it may concern.-

Be it known that I, CHARLES M. XVORTH- INGHAM, a citizen of the United States, residing at Bradshaw, in the county of York and State of Nebraska, have invented a new and useful Chu rn, of which the followin gis aspeciiication.

The invention relates to improvements in working body-churns.

The objectof the present invention is to simplify and improve the construction of workin g body-churns and increase their power of agitating the lacteal iiuid and more quickly produce butter than has heretofore been possible.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is an end view.

Referring to the accompanying drawings, 1 designates the frame, consisting of the sides 2, that are connected by cross-pieces 3 and 4, and the vertical standards 5, which are four in number, and are secured to the front of the frame. The upper end of the standards 5 are connected by top pieces 0. The upper bars 7 of the side frame have their upper edges 8 beveled toward their inner faces,and they form rails adapted to receive iianged wheels 0, which are adapted to fit the upper edges 8 and roll thereon without liability'of becomingaccidentally displaced. The upper side bars 7 are provided with the inclined rails 27, which make the track lower in the middle than at the ends, whereby when the churn nears the end of a stroke it travels upon an inclination, and its momentum is diminished as it is about to be reversed. The wheels 9 are rigidly secured to the sides of a churn-body 10, and are separated therefrom by conical washers or collars 11, and they have projecting outward from them journals 13, to which are secured connecting-rods 14 and 15, which are connected together by a cross-bar 16 and form a frame, which reciprocates and receives its motion from a weightpower, mounted in the vertical standard 5.

Serial No. 344,920. (No model.)

The rod 15 extends to the cross-bar 16, and the rod 14E extends beyond the said bar 1G, and is connected to a wrist-pin 17 of a drivewheel 18. The churn-body lO is preferably rectangular in cross-section, but may be of any desired construction, and during the operation of the machine it receives a recipro- 'cating motion ccmbined with a reversible rotary motion,the rotary motion being reversed at the end of each stroke. It will thus be seen that a thorough and complete agitation of the laeteal Iiuid is obtained and butter is quickly produced.

The power mechanism or motor for operating the churn consists of a winding-shaft 19, to which is connected a rope 20, that passes over a pulley 21, that is mounted in top bars 6, and the end of the rope is provided with a weight 22, that rotates the windingshaft and furnishes power for the motor. The windingshaft has mounted thereon a cogwheel 23, that is provided with a suitable clutch, and it meshes with a pinion 2i, that is mounted upon a shaft 25, that is journaled in suitable bearings of the vertical standards and a bracket secured to the inner face of the standard. The outer end of the shaft is provided with a drive-wheel that is journaled in the bar 15 of the connecting-frame. The motion of the churn-body, in a large measure, regulates the unwinding of the weight, which moves vertically in the space inclosed by the standards.

It will readily be seen that the churn-body is centrally mounted, and requires but com paratively little power to operate it, and that its contents are thoroughly agitated and butter is soon produced. The motor can be wound and the churn operated thereby without necessitating any mechanism for regulating the stroke of the machine.

1. The combination of the frame provided with the rails 7, having theirupper edges beveled, the churn-body provided with ianged rollers or wheels 9, rigidly secured to it and adapted to engage the rail 7, and the reciprocating frame consisting of the connectingbars 14 and 15 and thc cross-piece 16, substantially as described.

2. The combination of the frame having the rails 7, provided with beveled edges S, the

IOO

churn-body provided with rollersor Wheels 9 and having the conical Washers or collars interposed between the wheels or rollers andits sides and provided with journals 13, the oonneoting-fraine consisting of the bars 14E and 15 and the cross-piece 16, and a suitable Inotor imparting a reciprocating motion to the connecting-frame, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afixed my signature 1n 1c presence of two Witnesses.
